Lost Keys — Same-Visit Rekey

Your purse was taken from the back of a chair at a restaurant. The cards can be cancelled by phone tonight, but the house keys were in the side pocket beside a driver's licence that shows exactly where those keys fit.

Request a visit

In plain words

The visit runs in a steady order. On the phone you describe what was lost, which doors it opened and whether you have a way in. At the door the locksmith confirms your connection to the property, then walks it with you listing every cylinder. Each one comes off in turn, is repinned to the new key and refitted. The first key is cut to the new combination and checked in every lock, and the remaining copies are cut from it. Then every key is tried in every door with you watching, the count is agreed, and the new key code is written down for future copies.

Sound familiar?

A roommate moved out on bad terms and says the key was left on the counter. It was not. You have already changed the Wi-Fi password, but the front door still opens for a key that could be anywhere.

How the visit goes

How the visit goes

Hands using a yellow-handled screwdriver at a steel deadbolt plate on a dark door, with a steel knob below.
  1. 1

    Reading each cylinder before it comes off the door

    Every cylinder on the list gets a close look while it is still in the door. The keyway shape and the maker's stamp tell the locksmith which pin kit fits and whether the keys can be cut on the van. The feel of the plug with a working key, if one exists, says whether the pins and springs are healthy or tired. Corrosion on the face, a wobbly plug or a key that needs a jiggle points to a cylinder that will benefit from cleaning or replacing while it is out. A homeowner-rekeyable cylinder, recognisable by its small reset slot beside the keyway, calls for a different tool and gets noted.

  2. 2

    Resetting a homeowner-rekeyable cylinder without its key

    Some newer residential locks carry a small slot beside the keyway that lets a homeowner change the key with a learn tool, but only while a working key is in hand. When that key is the one that was lost, the locksmith uses the manufacturer's reset tool instead: the cylinder is pulled from the lock, seated in the reset fixture, and its internal sidebar and wafers are returned to a blank state. A new key of the right blank is then inserted, the learn tool sets the cylinder to it, and the lock goes back on the door taking the new key and rejecting the old one.

  3. 3

    The old key is now a piece of brass

    Whatever became of the lost key, it stopped mattering the moment the last cylinder went back on the door. It still slides into the keyway, because the keyway did not change, but the pins inside no longer line up with its cuts, so it turns nothing. Whoever finds it in a snowbank in April, or already has it in a drawer, holds a shape that fits your lock and does nothing to it. That is the whole purpose of the visit, and it is worth pausing on: the worry that started the day has a definite ending, and you can watch it demonstrated with the old key in your own hand.

What affects the quote

  1. 1

    Travel to the property

    Every call-out includes the drive. A house across town and a rural property at the end of a concession road involve different time on the road, and the quote reflects the trip.

  2. 2

    Electronic credentials on the same ring

    Clearing a garage opener's memory and re-pairing remotes, changing keypad codes or helping report a building fob are small tasks the quote names separately.

  3. 3

    Condition of the cylinders

    A clean, healthy cylinder is repinned as is. One clogged with salt and grit is cleaned first, and a worn or damaged one is replaced rather than repinned, each priced as its own item.

Same fees day, night or weekend.

Lost Keys — Same-Visit Rekey: questions

Advice · (289) 813-6380

Does the locksmith need to see the actual lost key, or just look at the lock?

Just the lock, and the door it is fitted to. A rekey works on the cylinder itself: the locksmith opens it, fits a new set of pins matched to a fresh key, and the old key stops working the moment that is done, whether or not it ever turns up again. Knowing roughly how the old key looked, cut on both edges, a chip on the head, a certain brand, can still help identify which cylinders in the house shared that key.

Should I rekey after a renovation or when a cleaner stops coming?

It is good practice whenever a key has been out of your hands for a while and you are not certain it came back. Contractors, cleaners, sitters and short-term guests all have honest reasons to hold a key, and most return it, but a rekey at the end of the arrangement is what turns 'probably' into certainty. Some households make it a habit at the close of every project.

Can all my doors work on one key afterwards?

Usually, yes. Cylinders that share a keyway family accept the same blank, so they can be pinned to one combination during the rekey. The front door, back door, garage entry and a gate padlock of the same family become a single key. Where a door uses a different family, the locksmith can swap its cylinder for a compatible one in the same visit, or you can choose to keep two keys for that door.

What the census means at the door

27%

Newer homes. About 27% of homes in Oakville were built in 1980 or earlier, according to the 2021 Census.

Where most homes are recent, the doors themselves are sound and the work is mostly about keys and control: who holds them, whether contractor keys were retired, and whether one key can open everything. The visit is often more conversation than drilling.

59%

A mix of homes. Single-detached houses make up about 59% of homes in Oakville (2021 Census).

Neighbourhoods of houses beside townhouses and low-rise buildings have a range of door constructions: solid wood, steel, fibreglass and metal-clad. A locksmith who works in such an area is used to fitting hardware to all of them without new holes.
